ROS

ROS1 is a gene that encodes a receptor tyrosine kinase involved in cell growth and differentiation. Alterations in ROS1, such as gene fusions, are found in a subset of cancers, including non-small cell lung cancer and certain types of sarcomas. These fusions lead to the production of abnormal ROS1 proteins that drive uncontrolled cell proliferation and tumour growth. Identifying ROS1 gene fusions in tumours is crucial for guiding treatment decisions, as targeted therapies, specifically ROS1 inhibitors, can effectively block the activity of these aberrant proteins. These inhibitors have shown promising results in reducing tumour size and improving patient outcomes. Understanding ROS1's role in cancer allows for personalized treatment strategies, providing more effective and tailored therapeutic options for patients with ROS1-positive cancers.
